The Surveyor in this image is William Moylan. I met William last year while he was surveying the placement of a caisson in pier 6 during it’s installation. I shot some photos of him that morning and ultimately chose one for a blog post. William saw the photo and thanked me for sharing it with the world. At the time he said to me that no one ever takes pictures of the surveyor. Later as we got to know each other he told me that his Mom in Ireland was able to see what he did for a living and the job he was working on because of that photo.

I was waiting for the crew boat yesterday when I saw William and a Carpenter working together. I liked the angle that I had and started shooting them discussing the task they were both working on. In this image they are making plans for William to ride up in the aerial lift to check the platform being placed for a hammerhead form that the carpenters are building on pier 8.

In this image you can see the floor of the hammerhead form that William and the Carpenter are leveling. William has climbed out onto the form floor with his measuring equipment and the Carpenter is moving into place underneath the form to make leveling adjustments.

Both of these images are three frame bracket sets of +2, 0 and -2 EV exposures that have been merged in NIK HDR Efex Pro 2 and finished in Aperture 3. For the top image I had to sue 100% anti-ghosting to eliminate the ghosting of the figures. In the second image I was able to get by with only 60% anti-ghosting. My advice regarding anti-ghosting is to strive for the lowest amount you can use in order to minimize halos and still achieve a reasonable final result.

Climbing Up Inside The Tower Crane on Pier Four of The Ohio River Bridges Project

Last week I was cleared by the safety manager to enter and climb the tower crane that has been installed on pier four of the Ohio River Bridges Project. The tower crane is approximately 100 feet tall now and will eventually be extended up to around 200 feet in order to build the bridge towers for the northern tower of the downtown span. Each section of the crane tower is ten feet tall and affords me a place to stand and shoot from as I climb up. I only went up six sections but with the additional height of the tower base I was able to shoot from around eighty feet above the river. The view of the project from there is amazing and I can’t wait to climb higher the next time I’m out there. Eventually I will be able to climb all the way up to the crane itself and see the project as the crane operator sees it.

In this second image you can see the base of the eastern leg of the northern bridge tower and the shadow of the tower crane. I think I was around forty feet above the base but I’m not sure exactly which level I was on when I shot this image. The river was pretty muddy from the heavy rains that went through upstream from Louisville a few days earlier. The brown shapes on the water are driftwood branches and logs that are swept into the river whenever the river rises.

Not much more to say about these images except that they are both HDR shot handheld in a three frame bracket set of +2, 0 and -2 EV exposures. They were merged in NIK HDR Efex Pro 2 and finished in Aperture 3.

Work On Southbound I-65 Bridges and Roadway Progresses

The southbound I-65 work is progressing well as the Walsh Construction crews build the new bridges and roadway that will replace the old I-65 infrastructure. In this photo you can see the steel bridge decking being installed in the center of the image while an Ironworker welds the supporting angle iron in place. I chose this image because I like the way the figures are arranged from the foreground through the frame. I also like the way the welding arc is sparking and the way the welder is positioned in the image.

As in most of my work this too is a HDR image created from a three frame bracket set of +2, 0 and -2 EV exposures. I had to use an anti-ghosting setting of 100% in NIK HDR Efex Pro 2 to address the many different poses the figures were in between frames. The ability to shoot handheld images of people movin

This second image also shows the Ironworkers welding and placing the steel bridge decking. The decking will support the concrete during the pouring of the roadway after the Ironworkers place reinforcing rebar across the completed bridge deck prior to pouring of the concrete. Once again you can see the power of the NIK HDR Efex Pro 2 anti-ghosting feature, especially in the way it has rendered the woman’s leg as she kicks the steel decking into place. As in the previous image I had to use a setting of 100% anti-ghosting in order to freeze the action and avoid ghosting artifacts.

I really liked the way the pre-stressed concrete bridge beams cast their shadows on the ground below them and the strong movement their placement gave to this image. This is also near Slugger Field where the new roadway is taking shape overhead. Once these bridges and roadways are completed traffic will be moved over onto this new roadway and demolition will begin on the old southbound I-65 infrastructure which will be replaced with new bridges and roadway. Once again I followed my normal HDR workflow of NIK HDR Efex Pro 2 and Aperture 3 processing.

This final image in today’s post is once again from beneath the concrete bridge beams for the new southbound I-65. I shot this using my 12-24 mm Nikkor lens and decided to take it into Photoshop CS5 after merging the bracket set in order to correct the lens distortion inherent in such a wide angle shot. This too is a HDR image created from a three handheld frame bracket set merged in NIK HDR Efex Pro 2 and finished in Aperture 3.

HDR Image of 127 Feet Tall Caisson

Last Wednesday the Ironworkers placed a 12 foot diameter, 127 foot tall caisson in the pier near the Kentucky shore. It weighed over 170,000 pounds and was going in one of the deepest piers of the project. Watching them lift it from a horizontal position into a vertical position was amazing. It took two cranes to do it and the coordination required was incredible.

This HDR image is from a three frame handheld bracket set consisting of +2, 0 and -2 EV exposures. I took the three frames into NIK HDR Efex Pro 2 where I merged them and applied the Balanced preset. While there I set the Detail slider to accentuated and the Drama slider to deep. In order to suppress some serious halos that were showing up along the vertical elements in the sky I reduced the Method strength slider until the halos were gone. I then took the merged file back into Aperture 3 for final adjustments to colors, sharpening and contrast.

 

HDR Construction Images of a Morning in November 2013

Today’s post is rather long on images yet short on words. I decided that what I wanted to show my readers was a series of several HDR construction images from a morning in November 2013. I thought sharing these HDR images from a single morning shoot would help my readers see how busy things are on the Ohio River Bridges Project.

I am always amazed at the skill and expertise that is required to do the work of Heavy Highway and Bridge Construction. Ironworkers, Carpenters and Operating Engineers must choreograph so many moves into placing the pieces of a single pier. The skill and commitment  to safety that they use to get the massive components in place is a sign of their professionalism and dedication to their respective trades. Any miscalculation when handling these pieces could result in slowing or stopping construction or even worse the very real possibility of the loss of someone’s life. For that reason the attention paid to properly performing each element in the process is paramount to safely accomplishing the task at hand.

I hope these HDR construction images help reveal the size and scope of the Ohio River Bridges Project as well as the my admiration for the skilled tradesmen and tradeswomen who perform these critical tasks. I also hope that the next time you see a construction site or meet a construction worker you will see their contribution to our way of life and the valuable part they play in building the world. Maybe you’ll even have a little more understanding of the important role that organized labor plays in providing skilled professionals that construct safe and dependable infrastructure for our world.

One final note about these images. All of the images in this post were created from three exposure bracket sets of +2, 0 and -2 EV exposures. They were merged in NIK HDR Efex Pro 2 and finished in Aperture 3. I use NIK HDR Efex Pro 2 because it does the best job I have found of reducing, and in most cases eliminating, ghosting when working with active subjects such as the men and women in these images. I finish the merged images in Aperture 3 because it allows me to control all the other variables such as color, contrast, sharpening etc in a non-destructive workflow.
